Description

Technical Field

[0001] This utility model relates to the field of casting core making, and in particular to a horizontal parting core making device. Background Technology

[0002] Currently, most companies use vertical parting core shooting machines. The sand-shooting cylinder shoots sand into the core box from above. After the conventional core is produced, the core box separates horizontally to the left and right to remove the core. However, some products cannot be designed with a left-right opening mold due to process and size limitations. They must be designed with a horizontal parting mold, that is, the core box is separated vertically. During production, the lower half of the core box is usually fixed. After production, the upper half is removed manually, and then the core is removed.

[0003] There are two problems with the production method: 1. When the core box is relatively light, manually moving the upper part of the core box is not a problem. However, with continuous development, some core boxes have become too heavy, with the upper part alone weighing over 20 kilograms. In this case, moving the core box manually becomes quite laborious, increasing labor intensity, safety hazards, and production efficiency. 2. The core shooting machine is a vertical parting core shooting machine. When the core box is parted horizontally, there is no core-topping mechanism. After the core is made, it is difficult to remove the core. It requires manual use of a pry bar to push the core-topping mechanism on the core box to remove the core, which will also reduce production efficiency.

[0004] Therefore, in order to overcome the above defects, the inventors propose a horizontal parting core-making device. Utility Model Content

[0005] The main purpose of this invention is to provide a horizontal parting core-making device, which can effectively solve the problems of low production efficiency caused by the need for manual movement of the core box and manual removal of the core in the existing core-making device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A horizontal core-making device includes a frame and two core box fixing frames mounted on a core shooting machine. A fixing plate is fixedly installed on the outer top surface of the frame, and a driving cylinder is fixedly installed on the outer bottom surface of the fixing plate. Two lifting guide rods are fixedly installed on the outer top surface of the fixing plate. A moving plate is slidably connected to the outer surfaces of the two lifting guide rods, and the output end of the driving cylinder passes through the fixing plate and is fixedly connected to the bottom surface of the moving plate. A lower core box is fixedly installed on the top surface of the moving plate. An upper core box is fixedly installed on one side of each of the two core box fixing frames. A collection assembly is provided on one side of the top surface of the frame.

[0007] Preferably, two movable rods are fixedly installed on the outer bottom surface of the lower core box, and a support plate is slidably connected to the outer surface of the two movable plates. A first spring is fixedly installed on both sides of the outer surface of the lower core box, and the two first springs are respectively sleeved on the outer ends of the two movable rods and fixedly connected to the support plate. Two inner top core rods are fixedly installed on the top surface of the support plate, and the top ends of the two inner top core rods extend into the interior of the lower core box.

[0008] Preferably, the top surface of the movable plate has two guide holes, and the top surface of the fixed plate is fixedly installed with an outer top core rod, and the two outer top core rods correspond one-to-one with the two guide holes.

[0009] Preferably, the collecting component includes a guide rail fixedly installed on one side of the outer top surface of the frame, and a slider is slidably connected to the outer surface of the guide rail. A fixing block is fixedly installed on the top surface of the slider, and a push plate is fixedly installed on one side of the fixing block. A second spring is fixedly installed on one side of the outer top surface of the frame, and the second spring is fixedly connected to the fixing block.

[0010] Preferably, a traction rope is fixedly installed on one side of the fixed block, and a second spring is sleeved on the outer end of the traction rope. A plurality of pulleys are provided on one side of the outer surface of the frame, and the traction rope rolls in contact with the plurality of pulleys.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] This utility model discloses a horizontal parting core-making device, such as Figure 1-5 As shown, it includes a frame 2 and two core box fixing frames 11 mounted on the core shooting machine. The core box fixing frames 11 are part of the core shooting machine structure. Since the core shooting machine is existing technology, and the core box fixing frames 11 are part of the core shooting machine structure, they are also existing technology, and therefore will not be described in detail here.

[0017] A fixed plate 3 is fixedly installed on the top surface of the frame 2, and a drive cylinder 1 is fixedly installed on the bottom surface of the fixed plate 3. The drive cylinder 1 drives the piston to move by compressed air, converting air pressure energy into linear mechanical energy.

[0018] Two lifting guide rods 4 are fixedly installed on the outer top surface of the fixed plate 3. The outer surfaces of the two lifting guide rods 4 are slidably connected to a movable plate 6, which can move up and down along the two lifting guide rods 4.

[0019] Furthermore, the output end of the drive cylinder 1 passes through the fixed plate 3 and is fixedly connected to the bottom surface of the movable plate 6, so that the drive cylinder 1 can push the movable plate 6 to rise and fall along the two lifting guide rods 4.

[0020] The top surface of the movable plate 6 is fixedly installed with a lower core box 9, and the two core box fixing frames 11 are fixedly installed with upper core boxes 10 on one side. When the lower core box 9 and the two upper core boxes 10 fit together, the core shooting machine can be started to complete the core making operation. A collection component is provided on one side of the top surface of the frame 2.

[0021] The entire device is installed on the core shooting machine. A release agent is applied to the cavity formed by the lower core box 9 and the upper core box 10 to ensure smooth demolding of the sand core. Then, the lower core box 9 and the upper core box 10 are preheated by the flame plate of the core shooting machine, so that the thermoplastic resin in the coated sand is melted by heat, which facilitates subsequent curing. The core shooting machine is started, and the coated sand falls into the sand shooting barrel of the core shooting machine through the hopper. Compressed air is injected into the sand shooting barrel at high speed through the injection head, and the coated sand is sprayed at high speed into the cavity formed by the lower core box 9 and the upper core box 10. Under the action of airflow, the coated sand compactly fills the cavity formed by the lower core box 9 and the upper core box 10. The sand particles are tightly arranged under the impact force and air pressure to form a sand core structure consistent with the mold. Then, the lower core box 9 and the upper core box 10 are kept at high temperature, and the resin undergoes a cross-linking and curing reaction under the action of heat.

[0022] Two movable rods 12 are fixedly installed on the outer bottom surface of the lower core box 9, and support plates 14 are slidably connected to the outer surfaces of the two movable plates. The support plates 14 can move up and down along the two movable plates, and the bottom ends of the two movable rods 12 are provided with limit plates to prevent the support plates 14 from falling off the two movable rods 12.

[0023] Two first springs 7 are fixedly installed on both sides of the outer surface of the lower core box 9. The two first springs 7 are respectively sleeved on the outer ends of the two movable rods 12 and are fixedly connected to the support plate 14. When the support plate 14 rises along the two movable rods 12, it will squeeze the two first springs 7.

[0024] Two inner core rods 8 are fixedly installed on the top surface of the support plate 14, and the top ends of the two inner core rods 8 extend into the interior of the lower core box 9.

[0025] The top surface of the movable plate 6 has two guide holes 13. The top surface of the fixed plate 3 is fixedly installed with an outer core rod 5, and the two outer core rods 5 correspond one-to-one with the two guide holes 13. After the core is made, the drive cylinder 1 drives the lower core box 9 containing the core to descend, so that the lower core box 9 is separated from the upper core box 10. The movable plate 6 descends along the two lifting guide rods 4, and the two outer core rods 5 will pass through the two guide holes 13 and contact the support plate 14, which will then push the support plate 14 to rise along the movable rod 12 and squeeze the first spring 7. The two inner core rods 8 will rise from the inside of the lower core box 9 to push out the core inside the lower core box 9.

[0026] The collecting component includes a guide rail 201 fixedly installed on one side of the outer top surface of the frame 2, and a slider 202 is slidably connected to the outer surface of the guide rail 201. The slider 202 can move along the guide rail 201. A fixing block 203 is fixedly installed on the top surface of the slider 202, so that the slider 202 can drive the fixing block 203 to move.

[0027] Furthermore, a push plate 204 is fixedly installed on one side of the fixing block 203, and a second spring 207 is fixedly installed on one side of the outer top surface of the frame 2, and the second spring 207 is fixedly connected to the fixing block 203.

[0028] A traction rope 206 is fixedly installed on one side of the fixed block 203, and a second spring 207 is sleeved on the outer end of the traction rope 206. A plurality of pulleys 205 are provided on one side of the outer surface of the frame 2, and the traction rope 206 rolls in contact with the plurality of pulleys 205. The end of the traction rope 206 away from the fixed block 203 passes through the frame 2 and the fixed plate 3 and is fixedly connected to the moving plate 6. When the drive cylinder 1 pushes the moving plate 6 to rise, the traction rope 206 will drive the fixed block 203 to move toward the direction of the second spring 207, and cause the fixed block 203 to squeeze the second spring 207.

[0029] When the drive cylinder 1 drives the moving plate 6 to descend, the compressed second spring 207 will push the fixed block 203 to reset, and the push plate 204 will push the ejected core to the guide plate 208, and slide it into the outer container through the guide plate 208 to collect the ejected core.

[0030] A guide plate 208 is fixedly installed on one side of the top surface of the frame 2. Multiple rotating rollers 2081 are rotated on the top surface of the guide plate 208. The guide plate 208 is inclined. When the core falls onto the guide plate 208, it will roll into contact with the multiple rotating rollers 2081, and then the core will slide along the guide plate 208.

[0031] The working principle of this utility model is as follows: First, remove the bottom tray of the existing core shooting machine, put the whole set of equipment into the core shooting machine, and fix the whole set of equipment and the body of the existing core shooting machine with bolts. Then, connect the air source of the drive cylinder 1 to the manual valve, and connect the upper core box 10 to the core box fixing frame 11 with bolts. Then, the core making work can be carried out.

[0032] Operating the manual valve causes the drive cylinder 1 to push the moving plate 6 upward, making the lower core box 9 engage with the upper core box 10. Simultaneously, the traction rope 206 moves the fixing block 203 towards the second spring 207, causing the fixing block 203 to compress the second spring 207. A release agent is then applied to the cavity formed by the lower core box 9 and the upper core box 10 to ensure smooth core demolding. Afterwards, the lower core box 9 and the upper core box 10 are preheated by the flame plate of the core shooter, allowing the thermoplasticity of the coated sand to be enhanced. The resin melts when heated, facilitating subsequent curing. The core shooter is started, and sand particles fall from the hopper into the sand shooting barrel of the core shooter. Compressed air is injected at high speed into the sand shooting barrel through the nozzle, spraying the coated sand into the cavity at high speed. Under the action of airflow, the coated sand compactly fills the cavity formed by the lower core box 9 and the upper core box 10. The sand particles are tightly arranged under impact and air pressure, forming a sand core structure consistent with the mold. Afterward, the lower core box 9 and the upper core box 10 are kept at high temperature, and the resin undergoes a cross-linking and curing reaction under the action of heat.

[0033] Then, by operating the manual valve, the drive cylinder 1 drives the lower core box 9 containing the core to descend, separating the lower core box 9 from the upper core box 10. The moving plate 6 descends along the two lifting guide rods 4, and the two outer core-pushing rods 5 pass through the two guide holes 13 and contact the support plate 14, which in turn pushes the support plate 14 to rise along the movable rod 12 and squeezes the first spring 7. The two inner core-pushing rods 8 then rise from inside the lower core box 9 to push out the core inside the lower core box 9. The drive cylinder 1 pushes the lower core box 9 to separate from the upper core box 10, reducing the labor intensity of manual labor.

[0034] When the drive cylinder 1 moves the moving plate 6 down, the compressed second spring 207 will push the fixed block 203 to reset, and the push plate 204 will push the ejected core to the guide plate 208, and slide it into the outer container through the guide plate 208 to collect the ejected core.
